Letting Go of What Is False

I have found that some of my so-called "facts" become fiction when challenged.
To transmute a "fact" into a falsehood takes a kind of alert discipline.
When I am holding on to a strongly held belief or mental/emotional state - something I believe to be a fact - I become aware of the emotions behind it. The resistance. The suffering.
I seem to find that the "facts" that have suffering underneath them wind up being strongly held beliefs.
So what is the use of this?
Finding out what is false is pretty important to me. The more and more I weed out the false in my life, the more and more something wonderful shines through.
The less cluttered my life is with the false, the more clear I am. The more I live in harmony. The depth of life occurs.
So what is the false?
Anything that causes conflict, pain, suffering, anxiety, fear - all psychological pain.
There are thing in this world that cause pain - a broken arm, the loss of a loved one but this kind of pain is not false.
The pain of fearing the future, anticipating some imagined event, is what I would call false. The actual event is real, the fearful anticipation of it is self-projected suffering.
Don't take my word for it. Take a look. See what is actual and what is just conceptual.
